Abstract
An image forming apparatus includes a duct through which air taken in from outside a housing is sent into the housing, a blower fan provided at an upstream end of the duct, a toner bottle provided facing a wall surface of the duct, and a fixing section provided on a downstream side of the toner bottle. A component-facing section facing the toner bottle is formed to be smaller in cross-sectional area than a fan placement section. Therefore, by absorbing heat of air around the toner bottle via a wall of the component-facing section, the component-facing section prevents the toner bottle from becoming hot.
Claims10
An image forming apparatus comprising:
- a blower fan that sucks in air from outside a housing and sends the air;
- and
- a duct though which the air sent by the blower fan is guided into the housing,
- wherein assuming that a direction that the air is sent through the duct is a blowing direction and an area of a cross-section of the duct orthogonal to the blowing direction is a duct cross-sectional area,
- the blower fan is placed in a fan placement section of the duct,
- the duct has a component-facing section, provided on a downstream side of the fan placement section in the blowing direction, that is smaller in the duct cross-sectional area than the fan placement section, and
- at least a part of a wall constituting the component-facing section serves as a part of a wall forming an accommodation space of an internal component that is disposed inside the housing.
